Yes, correct explanations : tante is a “complément d’objet indirect”, so never any agreement unlike for an”objet direct, and “je suis allé(e)” does agree like every past participle with the auxiliary “être” .
On téléphone”à” qq’un, that’s why it is indirect . Regarding the être auxiliary, the agreement rle is perenial except what in what I call the “false” être auxiliary, in some pronominal verbs . Ex : elle s’est fait gronder .
